What is the easiest way to remove an old Lower Wheel Collar?
A collar that has been installed for years may be difficult to remove due to having been in a wet environment for so long. We have found that this is the easiest way to remove the collar. First, drip some Liquid Wrench onto the set screw and the wheel’s shaft. Let it sit for several minutes, and then remove the set screw completely. Drip some additional Liquid Wrench into the hole in the collar where the set screw was installed. Let the Liquid Wrench work for a few more minutes, then use a pair of pliers, such as Channel Locks, and slowly but firmly rotate the collar on the shaft. It should break loose and be easy to remove after this. Clean the shaft with steel wool (not emory cloth or sandpaper), and lubricate with a good grease or petroleum jelly before installing the new wheel.
